It might work with a PC over the Bluetooth interface, but probably won't over the USB interface. Can't confirm this though since I only use a Mac myself.

I know the Mac side requires the SDK installed before tethering worked, as it included a package that installed updated files used by iTunes.

Also, I should mention some possible adds to the 'works/doesn't work' list (for beta 3); these were mentioned on hackint0sh and I have also confirmed:
AppStore apps that don't work:
Truphone (only stay up for a few seconds, then crashes)
WifiFinder (crashes on start)

JB apps that don't work:
BiteSMS (crashes at start)
